• Do not alter the original diameter of the spray head
nozzle .
• Do not leave the high pressure cleaner unattended .
• Do not move the high pressure cleaner by pulling on the
electrical cable .
• All electrical conductors MUST BE PROTECTED against
the water jet .
• The high pressure cleaner MUST ONLY BE CONNECTED
to a correctly earthed power supply .
• The high pressure may cause materials to bounce off
surfaces at speed; therefore protective clothing and safety
goggles MUST BE WORN .
• Before doing work on the cleaner, REMOVE the plug .
• Before pressing the trigger, GRIP the gun firmly to coun-
teract the recoil .
• Maintenance and/or repair of electrical components
MUST be carried out by qualified staff .
• DISCHARGE residual pressure before disconnecting the
high pressure cleaner hose .
• Before using the high pressure cleaner, CHECK every
time that the screws are fully tightened and that there are
no broken or worn parts .
• Only USE detergents which will not corrode the coating
materials of the high pressure hose/electrical cable
• ENSURE that all people or animals keep a minimum dis-
tance of 16 yd . (15m) away .
ASSEMBLY
• Connecting water hose to inlet first,and turn on the tap .
Make sure the machine is full of water . Then turn on the
main switch .The most important thing is not forget to
press the in electronic control center to start the machine .
• The electronic control center has three pressure modes
for users to choose . There are soft, medium and strong
mode .The pressure depends upon which attachment is
best suited to the surface you are cleaning .
• If you want to increase the pressure level, press the +
button in the electronic control center .
• If you want to reduce the pressure level, press the - but-
ton in the electronic control center .
• When you increase the pressure level to make the
pressure indicator turn red, it means that the machine is
working at the maximum pressure . At this time, please do
not let the machine work continuously for more than 15
minutes under the maximum pressure .
PRE-OPERATION
Adjusting fan pattern
Water can be sprayed either with a narrow jet or fan-
shaped . The kit includes 4 nozzles with a non-adjustable
spray angle of 0o, 15o, 25o, 40o . Install the required nozzle
before starting work, depending on the task .
Nozzle cleaning instructions
A clogged or partially clogged nozzle can cause a signif-
icant reduction of water coming out of the nozzle and
cause the unit to pulsate while spraying . To clean out the
nozzle:
1 . Turn off and unplug unit .
2 . Turn off water supply . Relieve any pressure trapped in
the hose by squeezing trigger 2-3 times .
3 . Separate lance from gun .
4 . Rotate nozzle to the narrow stream setting . This opens
up the fan blades .
5 . Using included tip cleaner, or an unfolded paper clip,
insert wire into the nozzle hole and move back and forth
until debris is dislodged .
6 . Remove additional debris by back-flushing water
through the nozzle . To do this, place end of a garden hose
(with water running) to end of nozzle for 30-60 seconds .
EXPLOITATION
When spraying water against a surface, maximum impact
is generated when the water strikes the surface "head on . "
However, this type of impact tends to cause dirt particles
to imbed in the surface, thereby preventing the desired
cleaning action .
The optimum angle for spraying water against a cleaning
surface if 45 degrees .
Spraying water against a surface at this angle provides for
the most beneficial impact force combined with efficient
removal of debris from the surface .
Another factor that determines the impact force of the
water is the distance from the spray nozzle to the cleaning
surface . The impact force of the water is increased as the
nozzle is moved closer to the surface .
DETERGENTS
The use of detergents can dramatically reduce cleaning
time and assist in the removal of difficult stains . Some de-
tergents have been customized for pressure washer use
on specific cleaning tasks . These detergents are approx-
imately as thick as water . The use of thicker detergents,
such as dish soap, will clog the chemical injection system
and prevent the application of the detergent .
The cleaning power of detergents comes from applying
them to a surface and giving the chemicals time to break
down the dirt and grime . Detergents work best when ap-
plied at low pressure .
The combination of chemical action and high pressure
rinsing is very effective . On vertical surfaces, apply the
detergent starting at the bottom and work your way up-
ward . This will prevent the detergent from sliding down
and causing streaks . High pressure rinsing should also
progress from the bottom to top . On particularly tough
